Comprehensive EvaluationM odel for Difficulty Coefficient ofRoad Adm inistration

The factors affecting the difficulty coefficient of road administration were analyzed, and a new model was proposed. In the mode,l the index system is established based on AHP (analytic hierarchy progress), and the road administration information is standardized based on fuzzy logic theory. Theweights from experts are tested with group consistency algorithm to obtain the normalized weights. Therefore, the difficulty coefficient of road administration is determined by calculating the group utility function based on the normalizedweights, utility function ofevery expertand the indexes.
